Finally, an easy-to-use, adaptive solution to sandbag training!

About the ULTIMATE SANDBAG Core Fitness System


The Ultimate Sandbag was created in 2005 by Strength Coach, Josh Henkin, as a means to help a severe back injury that both ended his athletic career and hampered him in his daily life.
Sandbag training showed great potential by being able to reach new muscles and help the stabilizers of the body, the same muscles Coach Henkin believed were weak and led to his injury.


The unique qualities and the effectiveness of the sandbag training inspired Coach Henkin to write his first book, “Sandbag FUNdamentals” in 2005. Excited about the potential of sandbag training, Coach Henkin also understood its limitations. Traditional sandbags are dirty, difficult to implement, and just plain awkward to use!

Determined to correct the inherent limitations of traditional sandbags, Henkin set to work designing an innovative tool with the demands of fitness and sports performance training in mind.

Adaptive Stability

While most other fitness tools have the same basic dimensions, the Ultimate Sandbag comes in three very different sizes. This not only allows the manipulation of weight, it allows the fitness professional to alter the level of stability of the training implement. The Ultimate Sandbag can be made variable in its stability — something no other training tool can match!


By being able to transform between varying levels of stability, the Ultimate Sandbag can be the perfect tool to create corrective exercises or for advancing to more complex movement patterns.


For more stable exercises, such as the Bear Hug Squat, the Ulimate Sandbag removes the challenge of teaching how to squat properly and puts the user in the proper position every time. This makes it possible for even the most difficult client squat right from day one!


More complex patterns, such as the Rotational Lunge, not only make for the most interesting multi-planar exercises, but these movements have been shown to burn more calories and create a significantly higher heart rate than popular fat loss exercises such as the kettlebell swing.
